JBJS. Br. 1992:74-B:431 - 435

Summary

Prospective trial. 33pts with 114 discs. Mean age 35yrs. T2 MRI looking at signal intensity from cental zone of disc. (normal, reduced, abscent) Disco after MRI (normal, tear with no leak, tear with leak, no nucleus)

All abnormal MRI had abnormal disco. 33 of 60 normal MRI had abnormal disco.

Critique

Good but small. New MRI techniques probably give better anatomy
